Refreshing a CollectionPropertyDescriptorPropertyModel doesn't Rename when collection is expanded

Grids for WPF Forum

I am modifying a property name from the SelectedObject, this property is part of a collection and I want it to be renamed in the Propertygrid at the same time that it is renamed in the selectedObject. Right now I am hooked to ObjectRenamed on the SelectedObject and I find the item in question, then I make item.Refresh(PropertyRefreshReason.ValueChanged). The thing is that it only update the name when the Collection in the PropertyGrid is collapsed, in other words, when I can see the item it doesn't get renamed.

I tryed doing a refresh on the parent item, but in that case I end up losing any expanded items in the collection and I want to avoid that to keep thing intuitive to the user.

Am I missing something or is there a workaround to that?

Thanks!

Hello,

Have you tried putting [NotifyParentPropertyAttribute] on the child property?  If the child property model's ShouldNotifyParentOnValueChange property returns true, then it should trigger the parent's value to refresh without requerying the children.

Hi,

I actually don't want to refresh the parent, since it will forget if any children were expanded. I want to refresh the children directly when this item is renamed from the SelectedObject, not directly from the Propertygrid.

I tried to override ShouldNotifyParentOnValueChange to send true all the time and override Name to add the property, but I don't see any change.

The Children is of type CustomCollectionPropertyModel that herit from CollectionPropertyDescriptorPropertyModel.

The collection itself is of type CustomPropertyModel that herit from PropertyDescriptorPropertyModel.

Would you be able to throw together a simple sample application that demonstrates the issue? Things like this can be difficult to support in a forum and a sample will help us best understand the exact issue and verify any product changes, if needed. If so, please send to our support email and remove any bin/obj folders from the project before you ZIP or else the attachment may be blocked. Please reference this forum post in the support email.

The answer was to call NotifyPropertyChanged(nameof(DisplayName)) on the item that was renamed.

The latest build of this product (v24.1.3) was released 1 month ago, which was after the last post in this thread.
